Under the background that the analysis and prediction of a project by huge Data (Big Data) are very popular, in the process of analyzing and predicting the project, various parameters, processing and analysis methods are often adjusted to carry out research, and even the same Data group derives various relay Data according to different research targets. The relay data can be regarded as a temporary File (Cache File) of the project, so that the additional time cost and the operation cost caused by executing the same project again to produce the relay data can be avoided when different analyses and applications are carried out subsequently.
In order to maintain the storage state of the storage space in a good state, a conventional method for maintaining the storage space deletes the temporary file in the storage space in a timely manner. For example, a common method for clearing storage space includes deleting a temporary file that is less frequently read and deleting a temporary file with a larger file capacity, or deleting some or all of the temporary files periodically to maintain the storage space. Since the temporary file is usually managed by a file with a smaller capacity, and the time cost for forming the temporary file is not considered, the conventional temporary file management method is not suitable for the temporary management of the relay file as described above when the generation time of the temporary file is longer as the capacity of the temporary file is larger.

Detailed Description
The detailed features and advantages of the present invention are described in detail in the embodiments below, which are sufficient for those skilled in the art to understand the technical contents of the present invention and to implement the present invention, and any person skilled in the art can easily understand the objects and advantages related to the present invention based on the disclosure of the present specification, the claims and the accompanying drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.
Referring to fig. 1, fig. 1 is a block diagram of a recording apparatus for storing a plurality of temporary files according to an embodiment of the invention. The recording apparatus for storing a plurality of temporary files in the embodiment includes a storage space 10 and a processor 20, and the processor 20 is electrically connected to the storage space 10, where the storage space 10 is, for example, a storage space of hardware with a storage function such as a hard disk, and the temporary file is, for example, obtained by the processor 20 executing a project, that is, the temporary file is, for example, a temporary file generated by the processor 20 during the process of executing the project, but the invention is not limited to the manner of obtaining the temporary file. The file size of the temporary storage file is different according to the difference between the size of the used original Data (project) and the processing mode, but if the original Data is huge Data (Big Data), the file size of the temporary storage file can reach the size range of more than dozens of GB or hundreds of GB, and the time required for executing the project to generate the temporary storage files can reach the time length of taking days as a unit along with the increasing size of the Data and the complexity of the processing procedure in the situation of processing or analyzing the huge Data.
Because the time cost for forming the temporary storage file is not considered by the existing management method, the file size of the temporary storage file suitable for the existing management method is about in the range of taking GB as a unit; the time cost and the file size for forming the temporary storage file are considered in the process of managing the temporary storage file, so that the method is more suitable for the situation of analyzing and predicting the project through Big Data (Big Data).
The storage space 10 may be a storage space 10 of an ata (Advanced Technology attachment) hard disk, an sata (serial Advanced Technology attachment) hard disk, an sas (serial Advanced Small Computer System interface) hard disk, a Solid-State Drive (SSD), or the like; the Processor 20 may be a Central Processing Unit (CPU), a Digital Signal Processor (DSP), or the like, and the storage space 10 and the Processor 20 are not limited to the above types.
For a more clear description of the embodiments of the present invention, please refer to fig. 1 and fig. 2 together, in which fig. 2 is a flowchart illustrating a method for managing a temporary storage file in a storage space according to an embodiment of the present invention, and the method for managing a temporary storage file in a storage space is applicable to a storage space 10 including a plurality of temporary storage files.
Please refer to step S10 of fig. 2: form a temporary file status table.
The processor 20 forms a temporary file status table, and the temporary file status table is stored in the storage space 10. The temporary file state table records a plurality of file names of the temporary files stored in the storage space 10 and a plurality of file states of each temporary file corresponding to a plurality of characteristics.
Step S12: and judging whether the storage state of the storage space accords with the health state or not.
In this step, the processor 20 determines whether a storage ratio of the storage space 10 falls within an expected ratio, wherein the storage ratio is preferably a ratio of the storage space 10 occupied; the anticipated proportion is preferably the upper proportion of the storage space 10 that can be occupied. When the storage ratio of the storage space 10 falls within the expected ratio, the processor 20 determines that the storage state of the storage space 10 is in accordance with the healthy state; when the storage ratio of the storage space 10 does not fall within the expected ratio, the processor 20 determines that the storage status of the storage space 10 is in accordance with the unhealthy status. In addition, the processor 20 may further determine whether the storage state of the storage space is in accordance with the health state every a preset time period, wherein the preset time period is, for example, 8 hours, 24 hours, and the like.
Taking percentage as an example of the storage space 10, the total storage space of the storage space 10 is 100%, and the expected percentage is, for example, 80%, which means that the occupied space in the storage space 10 preferably does not exceed 80% of the total storage space. That is, assuming that the total storage space of the storage space 10 has 100TB, when the storage space occupied by the temporary storage file in the storage space 10 is 90TB, the storage proportion is 90%, which exceeds the expected proportion by 80%, and thus it is determined that the storage state of the storage space 10 does not conform to the healthy state; on the contrary, when the storage space occupied by the temporary file in the storage space 10 is 60TB, the storage occupancy is 60%, so that the storage state of the storage space 10 is determined to be in accordance with the healthy state.
Therefore, when the storage status of the storage space 10 does not conform to the healthy status, step S14 is continued to form a temporary file sorting table. Otherwise, when the storage status of the storage space 10 is in accordance with the healthy status, step S16 is continued to end the method.
Step S14: forming a temporary file sorting table, deleting the last file name in the temporary file sorting table, and deleting the temporary file corresponding to the last file name in the storage space 10.
The processor 20 forms a temporary file sorting table, which records the file names of the temporary files stored in the storage space 10, and the file names of each of the temporary files are arranged according to the deletable level, so that when the temporary files in the storage space 10 need to be deleted, the processor 20 can delete the last file name in the temporary file sorting table according to the sequence listed in the temporary file sorting table, and delete the temporary file corresponding to the last file name in the storage space 10. A partial description of the formation of the temporary file ordering table will be described in detail below.
In addition, after the step S14 is executed to delete the temporary file corresponding to the last file name, the management method of the embodiment may continue to execute step S12, determine whether the storage state of the storage space 10 after deleting the temporary file conforms to the healthy state, and delete the last file name and the corresponding temporary file of the updated temporary file sorting table when the storage state of the storage space 10 does not conform to the healthy state, so as to reliably restore the storage state of the storage space 10 and maintain the healthy state.
If the processor 20 determines that the storage status of the storage space 10 after deleting the temporary file corresponds to the healthy status after executing the step S14 to delete the temporary file corresponding to the last file name, the processor 20 may delete the temporary file sorting table in the storage space 10, and continue to step S16 to finish the method, so as to save the storage capacity of the storage space 10.
In addition, the management method of the embodiment may be periodically executed, i.e., periodically updating the temporary file state table (S10), or periodically checking the storage state of the storage space 10 after forming the temporary file state table (S12), and starting to form the temporary file sorting table (S14) when the storage state of the storage space 10 does not conform to the healthy state, so as to timely maintain the storage state of the storage space 10. After the step S14 is executed to delete the temporary file corresponding to the last file name, the management method of the embodiment may also be a method that continues to the end of the step S16 and determines whether to execute the step S14 again based on the result of the next step S12, so as to reserve the temporary file stored in the storage space 10 as much as possible.
The operation of the management method shown in fig. 2 is described below by way of example. Please refer to fig. 2 in conjunction with table 1 below, wherein table 1 is an example of a temporary file status table.
TABLE 1
Taking the temporary file status table shown in table 1 as an example, the plurality of file names of the temporary file are A, B and C, each file name represents a temporary file, and each file name corresponds to each feature and has a corresponding file status, for example, the file status of the file name a corresponds to the feature "number of temporary files for project" is "5".
After obtaining the temporary file state table of the temporary file, if the processor 20 determines that the storage state of the storage space 10 does not conform to the healthy state, the corresponding label of each of the file states may be assigned to form the temporary file sorting table shown in table 2 below. The labels are preferably used to indicate the deletable levels of the file status of the scratch file for each feature, wherein the deletable levels are ordered from high to low, such as "deleted", "deletable", "can be left", and "must be left".
TABLE 2
The file names A to C shown in Table 2 are sorted according to the number of labels, wherein the labels are preferably used to indicate the deletable levels of the file states of the corresponding temporary files, and the deletable levels of the labels are sorted from high to low, such as "deleted", "deletable", "reserved", and "reserved". In detail, in the temporary file status table of table 1, each file status corresponds to a tag (for example, in table 1, the file status of file name a corresponding to the file capacity is 10G, so that the file status of "10G" can correspond to the tag "deletable" shown in table 2). Continuing with Table 2, the filename B has two "deleted" tags; the file name C has a 'must delete' label; the profile name a does not have a "must delete" label. The processor 20 can determine that the deletable level of the file name B is the highest and the deletable level of the file name C is higher than the file name a according to the number of the "must-delete" tags, so that the file name B is sorted at the last of the temporary file sorting table and the file name a is sorted at the top of the temporary file sorting table.
In another example (not shown in Table 2), if the file names A to C all have the same number of "deleted" tags, the processor 20 may then sort the file names A to C according to the number of "deleted" tags when forming the temporary file sorting table.
If the number of tags in each of the file names a-C is the same (not shown in table 2), the processor 20 may sort the file names a-C in the file sorting table according to the deletable level of the tag corresponding to the most important feature of the files, so that the file names corresponding to the most important feature with the higher deletable level are sorted later. In other words, if the number of tags at each level from the file name a to the file name C is the same, wherein the tag of the file name C is "deleted" in accordance with the feature of "number of temporary files of project" with the highest importance, and the file names a and B are "deletable" tags with the lower levels, the processor can also sort the file name C after the file names a and B.
The plurality of characteristics of the temporary storage file may include "temporary storage file generation time", "last execution time", "temporary storage file number of the project", "number of uses", "file capacity", "number of reference executions", and "last execution time of the project", etc. It should be noted that the features described are merely exemplary, the number and types of features of the present invention are not limited in this list, and the processor 20 may adjust the number and types of features based on user instructions.
In detail, the "temporal file generation time" is preferably the time cost and calculation cost required for generating the temporal file when executing the project, for example, the higher the time cost for generating the temporal file, the lower the deletable level thereof; the "last execution time" is preferably an interval from the time when the temporary file is read last to the current time, and may also be an interval from the time when the temporary file is generated to the current time if the temporary file has not been read after the temporary file is generated; the "number of temporary storage files for project" is preferably the total number of temporary storage files generated when the project for generating the temporary storage files is executed; the "number of uses" is preferably the number of times the scratch file is used/read; "file capacity" is preferably the capacity of the temporary file in the storage space 10; the "reference execution times" is preferably the times that all the temporary files having the same or similar generation steps as the temporary file are executed in a system having a plurality of storage spaces including the storage space 10, and the higher the reference execution times, the lower the deletable level, so as to avoid the erroneous deletion of the temporary files that may be executed many times in the future; the "project last execution time" is preferably the time when the project generating the temporary storage file was executed last time, or the time when the temporary storage file is generated, and the closer the project last execution time is to the current time, the lower the deletion level is, so as to avoid the mistaken deletion of the temporary storage file which may be used in the near future.
In summary, as shown in table 1 and table 2, the temporary storage file status table is used to present the file status of each feature corresponding to the temporary storage file, and the file names in the temporary storage file sorting table are arranged according to the number of the labels corresponding to the file statuses, so that the file names of the temporary storage files are sorted from the file name of the temporary storage file most needed to be retained to the file name of the temporary storage file most needed to be deleted in the temporary storage file sorting table. In table 2, the file name of the temporary storage file that needs to be reserved is a; the file name of the temporary storage file which should be deleted is B. However, the file name of the temporary storage file to be deleted can be sorted to the file name of the temporary storage file to be reserved, and the invention is not limited by the sorting method of the file names.
After forming the temporary file status table and determining that the storage status of the storage space 10 does not conform to the healthy status in step S12, step S14 is executed to form a temporary file sorting table, and delete the last file name in the temporary file sorting table and the temporary file corresponding to the last file name in the storage space 10.
Please continue to refer to step S14 of fig. 2 (forming the temporary file sorting table, deleting the last file name in the temporary file sorting table, and deleting the temporary file corresponding to the file name in the storage space 10) and match table 2.
Taking the temporary file sorting table shown in table 2 as an example, the processor 20 deletes the file name B and deletes the temporary file B (hereinafter referred to as "file B") corresponding to the file name B in the storage space 10, so that the temporary file sorting table in table 2 only has the file names a and C; only the temporary file A corresponding to the file name A (hereinafter referred to as "file A") and the temporary file C corresponding to the file name C (hereinafter referred to as "file C") are stored in the storage space 10, so as to update the temporary file sorting table.
Referring to step S14 of fig. 2 and taking table 2 as an example, after deleting the file name B and the file B in the storage space 10, if the storage state of the storage space 10 is determined not to be in the healthy state in step S12, the file name C in the updated temporary file sorting table and the file C in the storage space 10 are deleted. Accordingly, the storage space 10 can be prevented from being occupied by the temporary files with lower importance, and the temporary files with higher importance can be prevented from being deleted by mistake while the storage space 10 is adjusted, so that the state of the storage space 10 can be maintained in a healthy state.
Fig. 3 is a partial flowchart according to steps S0 and S14 shown in fig. 2. In order to more clearly illustrate the details of step S0 and step S14 and how to specify the corresponding label of each file status in the embodiment of the present invention, the temporary files include a first temporary file (file a), a second temporary file (file B), and a third temporary file (file C); these labels include a first deletable rating label (deleted), a second deletable rating label (deleted), and a third deletable rating label (left available) for illustration.
Please refer to fig. 3 in conjunction with the example of the tag assigned to the file state by the processor 20 shown in table 3, i.e. table 3 shows a transient table in the process of forming the temporary file sorting table according to the temporary file state table when the processor 20 is operating in the background, rather than the temporary file sorting table arranged according to the final deletable level.
TABLE 3
| Grade name | File capacity | Number of times of use |
| A | Can be deleted | Can be deleted |
| B | Can stay | Can stay |
| C | Must be deleted | Can stay |
The management method of this embodiment may further include step S0: setting a separation parameter for separating each label. It is noted that the step S0 can be performed before the temporary file state table is formed, or before the temporary file list is formed. That is, the user can set the separation parameter between two adjacent tags to assign the corresponding tags according to different file states. Taking the feature of "number of times of use" as an example, the user can set the separation parameter between the label "can be left" and the label "can be deleted" corresponding to the feature of "number of times of use" as "20 times", so when the file status (number of times of use) corresponding to the feature of "number of times of use" is more than 20 times, the corresponding label is "can be left"; when the file status is 15-20 times, the corresponding label is "deletable".
The aforementioned step S14 further includes the substeps of steps S141, S143, S145 and S147. In detail, please refer to step S10: form a temporary file status table. That is, the processor 20 forms a temporary file state table to record the file state of each feature of the temporary file, and the processor 20 can update the temporary file state table periodically, or the processor 20 can update the temporary file state table in real time when the temporary file state changes.
In step S10, the file status of each temporary file corresponding to each feature is recorded, and after determining in step S12 that the storage status of the storage space 10 does not conform to the healthy status, the processor 20 performs the sub-step S141 of step S14: and assigning a plurality of labels corresponding to the file states to the characteristics of each temporary storage file.
The file capacity feature is described below, wherein the processor 20 may assign the labels corresponding to the file states according to the partition parameter, or assign the labels corresponding to the file states according to the relative relationship between each file state (e.g. the relative size between each file capacity), which is not limited by the invention. In particular, for the "file capacity" feature, the tags of files A through C can be set according to the separation parameters as described above (e.g., when the separation parameter between the tag "reserved" and the tag "deletable" is "5 GB"; the separation parameter between the tag "deletable" and the tag "deletable" is "30 GB", a file can be given a "deletable" tag when the file capacity of the file is greater than 5GB and less than 30 GB). Alternatively, in the case where the user sets that the file capacity is larger and the file should be deleted, if the file C has the largest file capacity (file state) corresponding to the "file capacity" feature, and the file capacity of the file a is larger than that of the file B, in order to avoid the storage space 10 from being occupied with too much capacity, the file state of the file C is assigned with the "delete-required" tag having the highest deletable level, the file a is assigned with the "delete-capable" tag having a deletable level lower than that of the file C, and the file B is assigned with the "leave" tag having a deletable level lower than that of the file a.
In addition, in the case that the larger the file capacity set by the user, the more the file should be reserved, when the capacity occupied by one temporary file in the storage space 10 is larger than the capacity occupied by another temporary file in the storage space 10, the processor 20 may assign a label with a deletable level to the file state of the temporary file higher than the file state of the other temporary file when assigning the label corresponding to each file state. In other words, when the file size of the temporary storage file is larger, it means that the operation cost and time cost for generating the temporary storage file again are higher. Therefore, if the file capacity of file B is the largest of the three, and the file capacity of file C is the smallest of the three, the deletable level of file C may be the highest, and the deletable level of file B may be the lowest. Therefore, it is able to avoid mistakenly deleting the temporary file that needs to consume higher operation cost and time cost when generating again in order to save the storage space 10.
For example, the capacity of file A is, for example, 10 GB; the file B has a capacity of, for example, 50 GB; the file C has a capacity of, for example, 1 GB. Because the capacity of the file A is larger than that of the file C, the calculation cost required for regenerating the file A is higher compared with that of the file C; since the capacity of the file B is larger than that of the file a, which means that the calculation cost required for generating the file B again is higher than that of the file a, if the corresponding label is given according to the separation parameter, and the separation parameter between the label "can be reserved" and the label "can be deleted" is, for example, "80 GB"; if the separation parameter between the label "deletable" and the label "deleted" is, for example, "5 GB", the label of the file a is "deletable"; the label of file B is "deletable"; the label of the file C is "must delete". If the corresponding label is assigned according to the relative relationship between the states of each file, the label of the file A is "deletable", for example; the label of archive B is, for example, "Return"; the label of the archive C is, for example, "deleted".
However, the deletable level of the scratch file may not be fully positively or negatively correlated with the file size. In particular, in the case where the user setting is to adjust the deletable level of the scratch file based on a relationship between the file size and a size threshold, processor 20 may store the setting of the size threshold, and processor 20 may adjust the deletable level of the scratch file based on the relationship between the size threshold and the file size of the scratch file. The capacity threshold may be a proportional value of the entire storage space 10, such as an intermediate value of the entire storage space 10, or an intermediate value of the expected duty ratio, and the invention is not limited to the capacity threshold.
For example, in the range smaller than the capacity threshold, the processor 20 assigns the scratch file with a higher deletable level when the file capacity of the scratch file is farther from the capacity threshold (i.e., the file capacity is smaller); in the range larger than the capacity threshold, the processor 20 assigns the temporary file a higher deletable level when the file capacity of the temporary file is farther from the capacity threshold (i.e., the file capacity is larger); when the file size of the temporary file falls within the size threshold, the processor 20 assigns the temporary file with the lowest deletable level.
The capacity threshold may be a capacity range, and the processor 20 assigns the temporary file a higher deletable level when the file capacity of the temporary file falls outside the capacity range and is farther from the boundary of the capacity range. Otherwise, when the file capacity of the temporary file falls within the capacity range, the processor 20 assigns the temporary file with the lowest deletable level.
In other words, in the interval smaller than the capacity threshold or smaller than the lower limit of the capacity range, the smaller the file capacity of the temporary storage file is, the less the time cost for reproducing the temporary storage file is, so the higher the deletion grade can be; in the interval larger than the capacity threshold or larger than the upper limit of the capacity range, the larger the file capacity of the temporary storage file is, the higher the possibility that the storage space occupied by the temporary storage file affects the whole temporary storage operation is, and therefore the deletable level is also higher.
Accordingly, the corresponding label with the deletable level can be effectively given according to the file capacity of the temporary storage file, so as to avoid the storage space 10 from being excessively occupied while keeping the temporary storage file with more data.
The processor 20 then assigns a corresponding tag to the temporary file according to the file status corresponding to the "number of uses" feature. For example, if file B and file C are used equal and higher than file A, processor 20 assigns file A a tag of, for example, "deletable" for the file state corresponding to the "number of uses" feature; the label assigned to files B and C is, for example, "survivable".
Step S143: and counting the number of the labels of each level of each temporary storage file.
Continuing with the example of Table 3, processor 20 counts the number of tags in each level of each scratch file, and obtains a file name A with two "deletable" tags; the file name B has two labels of 'can stay'; the file name C has a "deleted" tag and a "reserved" tag.
The processor 20 then executes step S145: the file names of the temporary storage files are sorted according to the number of the labels at each level, and step S147 is executed: and deleting the last file name in the temporary storage file sorting list, and deleting the temporary storage file corresponding to the file name in the storage space.
According to the above statistical results, although the file name a has two "deletable" tags, the deletable level of the file name C is higher than that of the file name a because the file name C has a "must-delete" tag; since the file name A has two "deletable" tags, the deletable level of the file name A is higher than that of the file name B whose two tags are both "deletable". In other words, as shown in table 4 below, the processor 20 sorts the temporary files according to the number of each level tag to form a temporary file sorting table, and the temporary file sorting table shown in table 4 is the temporary file sorting table formed in step S14 of fig. 1. After the temporary file sorting table is formed, the processor 20 deletes the last file name in the temporary file sorting table and the corresponding temporary file in the storage space 10.
TABLE 4
| Grade name | File capacity | Number of times of use |
| B | Can stay | Can stay |
| A | Can be deleted | Can be deleted |
| C | Must be deleted | Can stay |
In addition, the tags can also comprise a highest-level tag and a lowest-level tag, so that the processor can more accurately adjust the temporary storage file sorting table according to the highest-level tag and the lowest-level tag, thereby avoiding the temporary storage files which absolutely need to be reserved from being deleted and really deleting the temporary storage files which do not need to be reserved.
For example, the highest level label may be "absolute delete"; the lowest level label may be "absolute reserved". For example, if a temporary file is read 360 days before the last time, and the file status corresponding to the "last execution time" feature is given an "absolute delete" tag, the temporary file can be moved to the last of the temporary file sorting table (i.e. the position with the highest deletion level) when the temporary file sorting table is formed; if a temporary file is given an "absolute reservation" label in the file status corresponding to the "file capacity" feature due to the large file capacity, the temporary file can be moved to the top of the temporary file sorting table (i.e. the position with the lowest deletion level).
Therefore, if the temporary storage file has the label of 'absolute deletion', no matter what other labels of the temporary storage file are, the temporary storage file can be ensured to be sorted at the end of the temporary storage file sorting table; similarly, if the temporary file has an "absolute reserved" tag, it is ensured that the temporary file is sorted at the top of the temporary file sorting table regardless of other tags of the temporary file. Accordingly, when the storage state of the storage space does not conform to the healthy state, the processor can determine that the deleted temporary storage file is deletable and retain an important temporary storage file to ensure that the storage space is properly utilized.
In summary, according to the management method of temporary storage files in storage space and the recording apparatus for storing multiple temporary storage files of one or more embodiments of the present invention, the temporary storage files can be automatically managed to reduce the requirement of expanding the storage space and ensure that the storage state of the storage space can be maintained in a healthy state. In addition, according to the management method of temporary storage files in storage space and the recording apparatus for storing multiple temporary storage files of one or more embodiments of the present invention, a temporary storage file with a large file capacity or a temporary storage file with a high operation cost for reproducing the temporary storage file can not be easily deleted, so that a temporary storage file with a high importance or a temporary storage file with a high reproduction cost can be truly reserved, and the deleted temporary storage file is a temporary storage file with a low importance or a temporary storage file with a low reproduction cost.
